The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000). The next three frames predict where this bird’s suitable climate may shift in the future—one frame each for 2020, 2050, and 2080.

The Eurasian Wigeon is an Old World species that is currently a rare but regular winter visitor along the Pacific Coast of Canada, Washington, Oregon, and northern California. Audubon's climate model projects that over half of the winter range will shift and that the total amount of climatically suitable area for wintering will sligntly decrease by 2080, both of concern. Projections for breeding range are not reported by the model because the species does not breed in North America.

Species Range Change from 2000 to 2080

The size of the circles roughly indicates the species’ range size in 2000 (left) and 2080 (right).

The amount of overlap between the 2000 circle and the 2080 circle indicates how stable the range will be geographically. Lots of overlap means the bird’s range doesn’t shift much. No overlap means the species will leave its current range entirely.
